' To all whom it may concern:

Be it known that ARTHUR A. BEACH, citizen of the United States, residingat Glendale, in the county of Los Angeles and State of California, hasinvented certain new and useful Improvements in a Screw-Driw. ingDevice, of which the following is a specification.

This invention relates to an improvement in tool holders constructedprimarily with a view .to permitting the convenient'operation of varioustools in places and under conditions in which the ordinary tool holderwould be of little service.

The invention is directed to a tool holder of comparatively compact formarranged to be supported for operation under ordinarily adverseconditions, the construction providing for convenient operation of thetool in either direction and for applying pressure to the tool duringoperation if the nature of the tool requires suchpressure.

The invention is illustrated 1n the accompanying drawing, in which: 5Fig. 1 is a View in "side elevation showing the tool with the parts in oerative relation.

line 4..-4 of Fig. 3.

F'g. 4 is a section on Fig. 5 is a partial plan of the handle showingthe latch means, whereby the same" may be connected to or disconnectedfrom thesupporting means. p The improved tool holder comprises a frame,including a cylindrical member 1, and an offset curved member 2 at oneend of the cylindrical member, the curved member terminating in abearing portion 3 at 0 right angles to and spaced beyond one end of thecylindrical .member. 'An operating shaft 4 is rotatably supported in thecylindrical member 1 and beyond one end of said member; is formed with'a-helical groove 5,

4 in whichis seated a 'pin 6 removably secured in afoperating handle 7.Thus by reci rocation of the handle, the operating sha t 4 is caused torevolve in the cylindrical bearing member 1. The shaft 4 extends beyondthe opposite endof the bearing member 1 and is loosely provided with abevel gear 8, and between the bevel gear 8 and the end of the frame theshaft 4 is rigidly provided with a ratchet wheel 9. A "double ended pawl10 is carried by the bevel gear 8, and the position ofthis pawl 1924.Serial no. 703,797.

relative to the ratchet determines the direction of rotation of thebevel gear, as will be obvious.'

A tool shaft 11 is rotatably vmounted in the bearing portion 3 of thecurved portion I of the frame, and this tool shaft carries a bevel gear12 normally in cooperation with the bevel gear 8, so that in theoperation of the bevel gear 8, the shaft 11 is rotated. The free end ofthe shaft 11 is provided with a socket 13 for the reception of anydesired type of tool, here indicated as a screw driver 14, a set screw15 serving to removably secure the tools within the socket.

'A supporting and pressure means is pro.- vided for the holder proper,comprising a threaded shaft 16 having at one end a bearing disc 17connected to the shaft by a universal joint 18, and cooperating at theopposite end with a threaded sleeve 19, having a terminal disc 20 forconvenient manipulation of the sleeve, from which disc projects abearing stud-or point 21'. A handle member 22 is pivotally connected at23 on the frame of the holder, the point of pivotal connection being inline with the shaft 11. This handle member projects'in line with andterminates adjacent the operating handle 7, the opposite end of thehandle member slidably; embracing the threaded shaft16 and bein providedwith a latch 24,[ whereby the ban 1e member may be fixed to the shaft 16at will and at any convenient point in its length. The operative end ofthe latch cooperates with the threads, or may bewithdrawn to permit afree sliding connection between the handle member 22 and the shaft 16. I

- In 0 eration, particularly in places where the or inary tool holdercouldnot be used, the improved-tool holder is positioned by ad'ustingthe holding member to cause the point 21 and ,disc- 17 to bear againstopposite parts of a fixture to support the tool holder for operation.The handle member 22 is then connected to the shaft 16, so thatunderfpressure on the handle end of'the handle member, the shaft 11,that is, the tool holder proper, is advanced towards its work. Theappropriate tool being placed in the socket 13, the handle 7 isreciprocated, and if the pawl 10 is properly positioned, the tool-14will be operated to the end de sired. Obviousl the shaft 4 is rotarilyreciprocated in t e movements of the handle 7, and it is apparenttherefore that the bevel gear 8 may be positively driven in eitherdirection at will through a proper setting of the pawl 10. Thus, forexample with the use of a screw driver tool, ascrew may be applied orwithdrawn.

Claims: I

1. A tool including a curved frame having a cylindrical memberprojecting therefrom, a tool shaft rotatably supported in the curvedframe at right angles to the cylindrical member, atool socket carried byone end of said tool shaft, an operating shaft mounted in thecylindrical member, a handle for operating said shaft, cooperating bevelgears on the operating shaft and tool shaft, to drive the latter in theoperation of the former, a supporting means including a threaded shaftterminally formed to permit said shaft to be rigidly held between spacedsupports, and a handle member pivotally connected with the curved frameand adjustable longitudinally of the threaded shaft.

2. A tool including a curved frame having a cylindrical memberprojecting therefrom, a tool shaft rotatably supported in the curvedframe at right angles to the cylindrical member, a tool socket carriedby one end of said tool shaft, an operating shaft mounted in thecylindrical member, a handle for operating said' shaft, cooperatingbevel gears on the operating shaftand tool shaft, tov drive tlfe latterin the operation of .the former, a supporting means including a threadedshaft terminally formed to permit said shaft to be rigidly held betweenspaced supports, and a handle member pivotally connected with the curvedframe in line with the tool shaft and adjustable longitudinally of thethreaded shaft. 3. A tool including a curved frame having acylindrical-member projecting therefrom, a tool shaft rotatablysupported in the curved frame at right angles to the cylindrical member,a tool socket carried by one end of said tool shaft, an operating shaftmounted in the cylindrical member, a handle for operating-said shaft,cooperating bevel gears on the operating shaft and tool shaft, to drivethe latter in the operation of the former a supporting means including athreaded shaft terminally formed to permit said shaft to be rigidly heldbetween spaced supports, a handle member pivotally connected with thecurved frame in line with the tool shaft and adjustable longitudinallyof the threaded shaft, and a latch on the handle member whereby oneendthereof may, be fixed against longitudinal movement relative to thethreaded shaft.
